Initial wiring was pretty much the same thing you would see anywhere. I could not find my 3.3v ttl converter so I used a Red LED and a 10k resistor on the RX of the ESP8266 (TX from usb-ttl converter) to try and stay in the 3.3v ballpark. I was able to flash with node-mcu (boot the module with GPOI0 LOW) . All went well and now it's time to learn what this whole .lua script thing is.

Any way here are some of the resources I used.
